ALL WHOM IT MAY CONCERN:

Be it known that I, JAMES TEACHOUT, of lllater'ordfin the county of Saratoga, and Stateot` New York, have invented a new and useful Improvement in Knitting-Machines; and Ldo hereby declare that the following is a full, clear, and exactv description of the construction and operation of the same, reference being had to the accompanying drawings, making a part of this specification, in which- Figure 1 represents a vertical central section of a. needle-cylinder with my invention applied thereto.

Figure@ is atop view of a portion of the jack-retaining collar, showing, in the continued red line, the point ot'vview in fig. 1'. i

The object of this invention is t0 adjust vertically the inner endsf of the jacke, or radial stitch or looplifters, by means of a movable disk, ring, collar, or hub, applied to hub or central portion of the needle-cylinder of knitting-machines, for the purpose of varying the kind of work to be done. t

A, iig. 1, is the hub or central part of a needle-cylinder, which turns on a stud or pin-shai`t,'b. c arethe needles. d shows the shaft which turns the take-upfand E is a collar secured thereto, and provided with adjusting-screws, ff, for the purpose of depressing the enclosing disk'or collar-G downward upon the rounded ends of the .jacks, thus formingjoints to said jacks by means of aeorresponding adjustable collar, H, under neath. The collar H, also, is loosely fitted to the hub or centre lof' the cylinder, nearly as shown, thus admitting of any required elevation or depression, in order to form close-knit and laygoodsfy Said collars H and enelosing-ring or plate G are so arranged that they may be easily adjusted in a vertical direction by means of the screws pressing downward and on the ring G, and similar ones pressing upward against the collar H, (said screws are not shown in the drawing, one screw being sulicicnt for the purpose or in any equivalent way, in order to eieot this much-desired end, to wit, to produce various kinds of work, as herei'nbefore mentioned.

The collar H or ring G are, either of them, provided with wings k t, at convenient distances apa-rt in the circular groove Z, as shown in fig. 2, for the purpose of' preventing the jacks M from being deranged at their inner ends where they are attached.

Having thus described my invention, what I- desire to secure by Letters Patent, is

l. The vertically-adjustable collars or rings G and H, for the purposes described.

2. In combination with the collars G and I-I, thepartitions o1' wings k and groove Z, asset forth.

3. In combination with the adjustable collars G and H, wings c, and groove l, the jacks" or lifters M,

formed as shown and described, and for'thepurpose specified.
